It i probably late for an answer, but I never received a notification about your question, sorry…
As I remember the main problem was that the UUID need inversion but not the services or other.
Another problem was that this Device does not perform well as LoRa sensibility compare to other products I am using. So for my projects this is not usable. I had difficulties to use it, thinking it was still a code problem…
I compared live with other products connected to a public antenna and ExploraBLE was working really badly.
I am very updet while I did not find a similar product yet on the market. LoRa-BLE.
PS: I found my post with more details: #226506
